RIBOSWITCHES: REFORMING OUR UNDERSTANDING OF METABOLIC REGULATION

Webb25 feb. 2024 · The ligand-induced conformational switch leads to an altered level of transcription or translation of the downstream gene, either lowering (OFF switch) or raising (ON switch) the level of expression. One of the largest groups of riboswitches bind coenzymes, including the relatively recently-identified NAD + -binding riboswitches ( 1 , 2 ). WebbImportantly, the inducible plants displayed wild-type–like growth properties and riboswitch induction resulted in a further increase in astaxanthin accumulation. Our data suggest that the mutant phenotype associated with constitutive astaxanthin synthesis is due to massive metabolite turnover, and indicate that astaxanthin accumulation is limited by the … burlington house cartoon
